Building of a hierarchy of wines based on terroirs: an initiative from the producers of Muscadet

Abstract

The Muscadet area is situated in the southeast of Nantes, close to the Atlantic coast. It constitutes the western extension of the French vineyard “Loire Valley”. The Muscadet is renowned and often spontaneously linked to a white wine.

However it remains misconceived as an ordinary wine, lacking authenticity. Proud of their wines, the Muscadet producers empowered themselves in an ambitious project dating back to the late 1980s. The essential aspects were established on: a fine selection of plots, distinctive vine growing practices and on a lengthening of wine maturation. This approach allowed them to rebuild the hierarchy of appellations, aimed at establishing strong “terroir” identification, which has led to the emergence of “crus communaux”.

The originality of the present study is twofold. First of all, it concerns implementing practical knowledge to identify the most capable fields to produce fine wines and to adapt oenological practices to express the variations of middle. Numerous questions need to be addressed, such as:

– what internal means does a vineyard have and which outside support mechanisms could the winegrowers successfully utilise to complete this step?

– The actors are also central to this study. How could so few innovators change the winegrowing process? And furthermore, how did the producers transform their vision about their natural environment, their knowledge base and their products? Finally, what are the features of these winegrowers, compared with the rest of the vineyard?

– The analysis is based on an intimate knowledge of the vineyard by the authors, coming from various scientific disciplines. Their account is established from a cartographic analysis on several levels. For example, on an enquiry questionnaire that included hundreds of winegrowers, and at meetings with the different actors who wanted to be part of this building process.

Sensory study of potential kokumi compounds in wine 

Kokumi is a complex sensation perceived as enhanced palatability. Under the influence of kokumi substances, foods/beverages tastes become more flavorful with increased intensity, spread, continuity, richness, harmony, and punch which are the six related characteristics corresponding to the kokumi sensory concept (Yamamoto & Inui-Yamamoto 2023).

Fingerprinting the origin of rosé wines with a new high throughput polyphenomics method

Wine is a widely consumed alcoholic beverage with a high commercial value. More specifically, the worldwide consumption of rosé wine has increased by 20% since 2002[1]. But because of its high commercial value, it can become a subject of fraud, and authenticity control is necessarily required. More than one hundred polyphenols have been recently quantified in various rosé wines [2]. They are key components defining color, taste and quality of wines. Their amount and composition depend on many different factors such as grape variety, winemaking and age of the wine. In this study, the influence of geographic origin of some rosé French wines was investigated. An original and very fast UPLC-QTOF-MS method was developed and used to predict the geographic origin authenticity of rosé wines.

Canopy photosynthetic activity and water relations of Syrah/R99 as affected by row orientation on a particular terroir

L’activité photosynthétique et les relations hydriques de plantes de Syrah sur R99 un mois après la véraison ont été étudiées dans un vignoble de la région de Stellenbosch. Le vignoble, planté à 2,75 entre rangs et 1,5 m sur le rang, sur un sol de type Glenrosa, était en pente et exposé a l’ouest: pour les rangs on avait adopté une orientation nord

Evaluation of intra-vineyard spatial and temporal variability of leaf area index using multispectral images obtained by satellite (Landsat 8, Sentinel-2) and unmanned aerial vehicle platforms

Estimation of vineyard leaf area index (LAI) is an important aspect for the winegrowers. However, tracking and monitoring are difficult tasks due to time constraints. Satellite and unmanned aerial vehicle (UAV) imaging have become a practical monitoring method for LAI. Nevertheless, for a proper LAI determination, the image’s spatial resolution is a key factor, since low-resolution images are incapable of distinguishing between adjacent vines due to the large area covered in each pixel, this leads to misinterpretation or generalisation of vineyard information.
